I need to show strings saved in an excel file, using a text component. Which is the sintaxis in the text component?. I tried $col asuming col the title of the excel column, but I didn´t got any result. Why?
In principle that is correct. Please should screenshots of your spreadsheet, loop and image text component. Have you changed the background to white (in which case you might have white text on a white background). Another common issue is size: .1 is large in height units but invisible in pixels.
Try reattaching the spreadsheet. According to the loop, the column is called chao not calculo
